Abstract

The entomotoxic effect of the dry powders of leaves of Annona muricata, Carica papaya, Citrus sinensis and Psidium guajava on the survival of Rhyzophertha dominica Fabricius (Bostrichidae: Coleoptera) and Sitophilus oryzae L. (Coleoptera: Curculionidae) was assessed in the laboratory. All the plant leaf powders exhibited various levels of toxicity, with Annona muricata exhibiting the highest potency of 90% for both insect pests and Carica papaya showing the lowest mortality of 60% for both insects at the end of the experiment. This study revealed that plant powders of can be used to efficiently to control S. oryzae and R. dominica in stored rice and its incorporation into traditional storage pest management is strongly recommended in developing countries.
